Visas:
Most Latin American countries don't require visas, but sometimes the regulations change. It would be a good idea to check with the embassy or consulate before your visit. Upon arrival you may have to fill out a customs form, so make sure to have a hotel address to put down, even if you end up staying somewhere else. Most countries allow visitors to stay for a maximum of 90 days. If you want to stay for any longer you can apply for an extension at the nearest immigration office. These extensions are usually granted.
